Lightweight Auto-Updating Project Tracker and Data Dictionary // Once initialized, the package leaves a 'tiny trail' of human- and AI-readable text that makes it effortless to keep track of small to medium-sized projects. The package is lightweight (hence 'tiny') and maintains a YAML trail file recording which scripts produced which output files. Call tinytrail() once at the top of each script to record metadata, wrap any save call with tinytrail_write() to log the output path, and optionally use tinytrail_dict() to capture a data dictionary for each input data frame.
